{"version":"1.0","type":"rich","title":"Fork of Choropleth Map with Interactive Filtering","description":"This choropleth map displays world economies, with countries colored according to their economic classification using an ordinal color scale and the `schemeSpectral` palette. Users can interactively filter the map by clicking legend items, which dims non-matching countries and highlights the selected category. The visualization uses `d3.geoPath` with the `geoNaturalEarth1` projection, `topojson` for geographic data, and supports zooming via `d3.zoom`. A color legend with clickable circles controls the filtering, while hover tooltips reveal country names and values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1f229ba1dd3a403d87c2e3afd3e3c540?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
